+A set of GnuPG public keys used by pkgsrc infrastructure.  Having them

+easily update the package when keys become obsolete and newer ones are
+issues.

+# Note that only the most recent keyid is exported rather than all of them,

+# with netpgp and still causes warnings if available in the keyring.
